6 globes employed in White-way? street lightmg. I

One of the objects of the invention is the provision of a globe'holdervwhich may be P permanently installed as part of the postequipment, and which may be brought beneath the globe for holding thesame, when desired, for instance when the globe is to be lowered andswung out of its normal position while the lamp tender is changing oradj usting the lighting elements.

Another object of the invention is to provide a globe holder of shadowless construction so that if desired it may, without dis-iadvantage, be maintained in position as the normal support or holder forthe globe.

Other objects of the invention will appear as the following descriptionof a preferred embodiment thereof proceeds.

In the. drawings in .which .the same characters of reference areemployed throughout the several figures to designate identical parts: 7V

Figure .1 is a front elevation showing the top of a lamp post with threelamps with globe holders carrying out the principles of the presentinvention in operative relation thereto; v

Figure 2 is a perspective view of one of the globe holders; and v V.

Figure 3 is a detail of that form of the globe holder shown in theuppermost lamp in Figure 1.

figures it may be stated that the glassglobes employed in connectionwith the intensive Y lighting of citystreets and much-traveled platformfor the lamp tender, to lower one Beforereferring in detail to theseveral of these globes and place it out oftheiway I while he isadjusting or changing the lighting elements of the lamp. Frequent breakages consequently occur so that the maintenance of this type oflampincludes a'substa-ntial item merely for unavoidable globe breakage. I I

Furthermore, the size of these globes is such that they present anextensive surface to wind pressure so that the flange of the globe withwhich'the usual supporting screws engage is frequently broken throughwind pressure permitting the globe to be blown off and, of coursesmashed. The need for an auxiliary holding or supporting means is thusapparent, and the present invention is designed-to meet such a need. 1

' Adverting now to FigureQof the draw. ings, the lamp holder consists ofa standard in general designated by the reference character 1 andconsisting of. a socket portion 2 and a rod portion 3 the lattertelescoping into the socket portion".

- Lateral arms 4 and 5 extend preferably radially from opposite ends ofthe standard, theupper arm at being provided with clamping means, thesame consisting of a cap 6' having a recess 6 and adapted to be securedto a corresponding portion of the arm 4 having a recess 7, the recessedportions 6 and 7 cap6 may be secured byany suitablemeans such as screwsand bolts, not shown, andthe mounting of the arm 4 upon the post isdesigned to be oflpermanent character.

In that form of the invention shown in Figure 2, the rod portion 3 isrotatable within the socket portion 2 and is also telescopicallyadjusted, a single set, screw 9 affording means for fixing therod foreither of-these adjustments The lower varm 5 is provided with globeholding means comprising an annulus 10 supported by a spider 11, thelatter being carried at the end of a rod 12 slidably and rotatablymounted in a suitable boss or collar 13 formed on or securedtothelaterjal arm 5. The rod 12 is adjustablevertically with respecttothe arm 5 and may. be held in. any

side of Figure 1;

position of adjustment by means of a set screw 14. The rod 12 ispreferably coaxial with the recess formed by the recessed portions 6 and7.

The operation of my improved holder for globes may be readilycomprehended from an inspection of Figure 1, referring to the two lowerlamps, the righthandone of which shows the holder in position withrespect to the lamp while at the left the holder is shown with theglobe, indicatedbydotted lines moved out of the way giving access tothe,

lamp elements. At the right hand side the globe holder is shownpermanently mounted, the annulus 10 supporting the globe in its normalposition. The globe holdermay be left in this position if desi--red=,-orthe lower lateral arm may be turned away from the globe as shown at theleft hand side. When the lamp tender desires to remove the globe, .h'eswings the holder until the annulus 10 is beneath the globe. The upperscrews 15, if are present, are loosened so that the globe may bewithdrawn fromthe lamp and rest in the annulus, The set screw 9' is thenloosened to permit the rod portions to be lowered with respect to thesocket portion 2 a sufficient distance to permit the upper end of theglobe to clear the part of the lamp with which it is associated. v

' While the set screw '9 is still loosened, the rod portion 3 togetherwith the lower lateral arm '5 bearing the globe inthe annulus 10 isrotated to the position shown at the left hand Thereis no danger of theglobe dropping from the hands of the attendant for it is stably seatedwithin the annulus 1 0 and even while the set screw 9 is loose, if theattendant should inadvertently letgo of the lower arm 5*, the unbalancedweight of the globe puts a tilting stress upon: the rodportion 3-causing it to-bind within the socket so that it will not drop out. Afterthe lamp has been tended, the lower arm 5 isv againswung. into placewith the rod 12 coinciding with the axis of the neck 8, whereupon thelateral arm and rod portion 3 are pushed upwardly until the globe isagain in its "normal position withv respect to the adj acen-t lampparts. The set screw 9 is thentightened,

If it is desired to have the lower lateral arm 5 and annulus 1O normallyout of the way,t11 e screws 15 or whatever other holding means may beprovided are tightened, the

s'ts ciew 9 is loosened, the rod portion 3 Figural, to loosen the screws15, and loosen the set screw 14,- thereby letting the annulus I0 descendwith the globes- The-globe can then be rotated by hand, at the same timea wiping cloth is applied to its exterior surface. Since the globesare'spherical, the annulus 10 affords a seat for any portion of theglobe excepting, of course, where it is open at the top part. Therefore,for washing the inside of the globe, it, is only necessary when it hasbeen sufieiently lowered, either by lowering therod 12 or the rodportion 3, to tilt the globe, in the annulus 10 until the open topportion comesto aposition convenient to the attendant, ,o

lt-maysometimes be desirable in lowering the globe prior to turning itout of the way, to leave the set screw 9 tight and to loosen the setscrew 14, thus lowering the annulus-10' and globe with respecttothelower lateral arm 5. 'Sincethe globe is then in balanced relation withrespect to thel-owered part, this operation is more easily performedthan by lowering the rod portion 3 and lateral'arm 5.

It; is preferred to make the annulus and spider 11 of wire, thusproviding a construction which is substantially shadowlessso that thereis no objection, if desired, to leaving the holder in its operativeposition as shown at the right hand side of Figure 1. Itis obvious thatthis provides a strong and rigid being blown down.

At the top part of Figure 1 is shown an adaptation of theglobe holderfor globes which are normally supported from beneath linstead of beingsuspended. In this form the globe holder does not serve as an aid to i.the attendant, but solely as a permanent auxby a dished member 16adapted tore'ceive and bear down upon the upper portion of the globe.For removing. thisgl'obe, it is necessary to loosen the set screw Sandtoraise and rotate the rod portion 3- and dished member 16.

It is to be understood that in the foregoing description of theaccompanying drawings, I have illustrated my improved holder for globesin elemental form, for the purpose of exemplifying its structuralfeatures, and that asactually manufactured and installed itmay beembodied in an ornamental form to harmoni 'zewiththe decorative motif ofthe post with which it is associated.

What I claim is: i i

3. An auxiliary support for depending 2 globes, comprising a bracket;means for clamping the bracket to some part of the main globe support; aring in which the globe may roll; and means borne by the bracket forsupporting the ring under the globe.

4. An auxiliary support for depending globes, comprising a bracket;means for clamping the bracket to some part of the main globe support; aring in which the globe may roll; and vertically slidable means,

borne by the bracket, for holding the ring against the globe when in itsnormal position and for supporting the globe in a temporary loweredposition.

5. An auxiliary support for depending globes, comprising a bracket;means for clamping the bracket to some part of the main globe support; aring in which the globe may roll; a rod borne by the bracket andsupporting the ring, vertically slidable under the centre of the lobe.

6.
